Matching Faces Against the Clock
This study examined the effect of time pressure on face-matching accuracy. Across two experiments, observers decided whether pairs of faces depict one person or different people. Time pressure was exerted via two additional displays, which were constantly updated to inform observers on whether they were on track to meet or miss a time target. In this paradigm, faces were matched under increasin...
متن کاملMg2+ protects adult beating cardiomyocytes against ischaemia.
Although Mg2+ reduces infarct size in whole heart models of ischaemia/reperfusion, the cardioprotective effect of Mg2+ at the cellular level is still a controversial issue. Therefore, we tested whether Mg2+ protects cardiomyocytes against ischaemia. To accomplish this aim we used an experimental model of ischaemia that utilises single beating adult cardiomyocytes in which oxygen tension is tigh...
متن کاملMutation in one Molecule Induces Beating Rate Changes by Affecting the Coupled Clock Pacemaker Function
Pacemaker function is orchestrated through molecules on the membrane and on the sarcoplasmic reticulum that are coupled by Ca2+ and post-translation modification signaling. These molecules and signaling cascades form one coupled-clock system. Experimental and computational evidence highlight the coupling between components in this system. However, most studies examine how a given pacemaker muta...
متن کاملQuantum methods for clock synchronization: Beating the standard quantum limit without entanglement
N), i.e., as the standard quantum limit. We introduce a protocol that makes use of Nc coherent exchanges of a single qubit at frequency ω, leading to an accuracy that scales as (ωNc) −1 logNc. This protocol beats the standard quantum limit without the use of entanglement, and we argue that this scaling is the fundamental limit for clock synchronization allowed by quantum mechanics. We analyse t...
متن کاملAsymmetrically localized proteins stabilize basal bodies against ciliary beating forces
Basal bodies are radially symmetric, microtubule-rich structures that nucleate and anchor motile cilia. Ciliary beating produces asymmetric mechanical forces that are resisted by basal bodies. To resist these forces, distinct regions within the basal body ultrastructure and the microtubules themselves must be stable. However, the molecular components that stabilize basal bodies remain poorly de...
